A 3.0kg- block sits on top of a 5.0kg block which is on a horizontal surface. The 5.0-kg block is pulled to the right with a force as shown in the figure . The coefficient of static friction between all surfaces is 0.65 and the kinetic coefficient is 0.42.
PART A: What is the minimum value of needed to move the two blocks?
PART B: If the force is 10% greater than your answer for (a), what is the acceleration of each block?
